Sigmund Freud pictured with one of the ever-present cigars he enjoyed regularly.

Freud, the famous psychoanalyst, postulator of the existence of libido; libido applies to A LOT of things: it's the energy with which mental process and structures are invested, so not just, you know, what you were thinking of). He also developed the free association therapeutic technique (I'll say a word. You say whatever comes into your head.) and discovering transference (Stop reacting to me like I’m your mother! I’m not her!!!) and loads of other influential psychiatry as we know it today. Our point, Sigmund knew how to stay sane, take it easy and enjoy life.

My boy! Smoking is one of the greatest and cheapest enjoyments in life, and if you decide in advance not to smoke, I can only feel sorry for you.
